Reading this stuff ought to convince everyone but the most radical humanist that evil exists and if it isn't opposed, will swallow us up.
In a chapter on basic sabotage and destruction, would-be assassins are offered various options, including "poison-making, poisonous gases and poisonous drugs." They are instructed on specific plant life that can be used to make poison gas, how to make the gas and what quantity is needed to kill a man.
All in the name of Allah, of course. Don't be duped by those who pretend this is just a small fringe. That's what America's enemies want you to think. They might be willing to sacrifice Afghanistan if that makes us think we're safe again. We are not safe and probably never will be again. What we should be is vigilant and let the assassins know that if they hit us, we will wipe out their families.
